I've had RCS for a couple years now. At one point I had several hundred in my 20g. Admittedly I let the tank to for some time and it became overgrown with stems. I also didn't feed very often. I trimmed the tank and got it back into shape, but Im now waiting for things to grow in as its pretty empty now. I've only got maybe 60 shrimp in there now after taking out 25 for my newly rescaled 46g. After two weeks there are still no berries shrimp. Many are saddled, but none are berried I changed the water and cleaned the filter. What am I missing? None of the ones in the 46 are berried either.

Time of the year. Shrimp seem to pick up on many things we don't, pressure possibly being one, etc. Like a lot of animals. Sometimes it's just not a breeding time of year, for whatever reason to them. Some people get no breeding over winter, others go nuts. Using fan's or heaters doesn't seem to be enough to trick them, so they probably pick up on other things we aren't aware of.

That said, some frozen blood worms always seems to get at least a few going for me when times slow down. The best thing to do this, is ride out, they will get there when they get there. Messing with water, changing more on them, screwing with everything is probably going to slow them down even more than give them and let them pick up on whatever clues they need to breed and try a few frozen blood worms though.

Thank you for all the ideas. I may need to add a new bloodline. And the substrate was very disturbed and there is some potting soil, so ammonia could play a part. I use just dechlorinated tap water and no C02 or ferts. I'm thinking they'll be more comfortable when I get some Fissidins in there as they have been moss less for quite a while. I didn't think to feed bloodworms. I have to get some for my new GBR in the other tank.

+1 to getoc idk if its a placebo effect but i dont see as many berried momma's when i get coldfronts moving in, a bigger thing imo is the genetic bio diversity always good to sell and put new blood into the colony for a stability/health. look into ebjd eletricbluejackdempsy and how having them being inbred so much and the effects of it all.
